E-Bike Charger Bosch 2A Smart System (BES 3)
The Bosch 2A Smart System Charger is a compact and lightweight charger for Bosch Smart System, also known as BES 3, e-bikes. It is an ideal choice for charging smaller batteries and is well suited for riders who want a charger that is easy to carry, store or use as a spare charger.
Compared with the Bosch 4A Charger, the 2A Charger is approximately 40% smaller, so it fits easily into a bag or travel kit for longer e-bike rides. With a charging current of up to 2 A, it provides steady charging and is especially practical for smaller batteries, range extender batteries and everyday charging.
The charger operates on 220–240 V and is intended for indoor use. The IP40 protection rating means that the charger is protected, but it must not be used outdoors. The operating temperature range is 0 to +40 °C, while the recommended storage temperature is +10 to +40 °C.
With a weight of approximately 525 g, an approximately 1.5 m power cable and an approximately 1.0 m battery cable, the charger is convenient to use at home, at work or while travelling. The Bosch 2A Smart System Charger is a practical solution for riders who prefer compact size, low weight and simple handling.

BOSCH eBike Systems is the world's leading manufacturer of e-bike drive systems, which started in 2009 as an internal start-up within German industrial giant Bosch. The idea came from two Bosch engineers — Peter Kimmich and Philipp Kohlrausch — who realised that four major megatrends (traffic in growing cities, an ageing society, climate change and carbon emissions) all converged on a single solution: an electrically assisted bicycle. The first prototype in 2009 was actually based on a power steering motor mounted onto a regular bicycle, held together with tape and cable ties — and from that humble beginning has grown today's de-facto industry standard. The first series-production motor reached the market in 2011 with 50 Nm of torque; today the flagship Performance Line CX delivers 85 Nm and is regarded as the gold standard in the e-MTB sector. The strength of Bosch eBike Systems lies in Bosch's own 140 years of engineering experience — the division draws on the group's expertise in batteries (cordless tools), electric motors, sensors and automotive electronics (Bosch is the world's largest automotive parts supplier). System integration is a hallmark of the brand: motor, battery (PowerTube and PowerPack), display (Kiox, Nyon) and the mobile app (eBike Flow) are all fully integrated and communicate via the Smart System — the platform on which Bosch also brought to market the first series-production e-bike ABS. As an independent division since 2020, Bosch eBike Systems today supplies its systems to more than 100 of the world's leading bike brands, including Cube, Trek, Cannondale, Riese & Müller, Haibike and Lapierre. The German way: if the Bosch name is on a product, it has to work flawlessly and last — just like their automotive, power tool and home appliance products.
